Abstract. If {p1(x\ ..., pq(x)} is a minimal integrity basis of the ideal of polynomial invariants of a compact coregular linear group G, the orbit map yields a diffeomorphic image $f = p(Rn) £ R β of the orbit space ΈZS/G. Starting from this fact, we point out some properties which are common to the orbit spaces of all the compact coregular linear groups of transformations of 1RΛ In particular we show that a contra variant metric matrix P(p) can be defined in the interior of
